LUBRICATING DEVICE.

SPECIFICATIQN forming part of Letters Patent No. 718,456, dated January 13, 1903. Application iiled January 27, 1902. Renewed November Z0, 1902l Serial No. 132,167. (No model.)

To all whom it may concern.-

Be it known that LFRED LINCOLN HAW- KINS, a citizen of the United States, residing at Gardner, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements innLubricating Devices; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

The invention relates to devices for lubricating guard-rails of railroad-tracks.

The object of the invention is to provide a device of this character which shall be simple of construction, durable in use, comparatively inexpensive of production, and by means of which the guard-rails of railroadtracks may be lubricated from a moving car or train, provision being made for heating the oil-tank and thereby preventing the thickening or coagulation of the lubricant.

With this and otherobjects in view the invention consists of certain no vel features of construction, combination, and arrangement of parts, which will be hereinafter more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 shows in conventional form the trucks of a motor or grip car, my invention being shown in longitudinal vertical section. Fig. 2 is an enlarged vertical sectional view of the lubrieating device adapted for usenpon a steam- Fig. 3 is a side view of the oil-tank, and Fig. 4 is a cross-sectional view looking downward on line :c c of Fig. 3.

Referring to the drawings, 1 denotes an oiltank, which may be mounted upon the carin Y any suitable manner and is provided in its lower end with a discharge-tube 2, leading downward toward the rail and adapted to discharge the lubricant upon the guard rail or flange.

3 denotes a valve-seat in the bottom of the tank, and 4 a needle-valve adapted to said seat and provided with a stem 5, which is guidedin its vertical movement by a bar 6, having a slot 7, through which the stem passes.

S-denotes a heating-coil or an electrical heater surrounding the oil-tank and designed ed upon the car-frame and has a pipe 11 communicating with the upper end of the oil-tank. The rod 12 of the plunger extends within convenient reach of the motorman and may be operated either by foot or by hand for the purpose of compressing air within the pump-cylinder and supplying the tank with such air.

13 denotes a valve located within the oiltank for controlling the admission of airv thereto and is formed with a curved stem 14, which is bolted or otherwise secured to the Vupper end of the stem of the needle-valve,

with provision for slight pivotal motion at the joint. Thecurved stern 14 is pivoted to a stud 15, secured to the cross-bar 6, as more clearly shown in Fig. 2 of the drawings. It is evident that upon compression of the air within the cylinder of the pump 10 the valve 13 will be forced from its seat, and this movement of the valve will'raise the needle-valve 4 from its seat. It will thus be seen that the air in the tank has two functions-namely, that of lifting the valve 4 from its seat and that of exerting a pneumatic pressure upon the co1- umn of liquid contained in the oil-tank for the purpose of forcing the same through the outlet in the bottom of the oil-tank.

In the construction shown in Fig. 2, wherein the device is adapted for use on a train of cars equipped with an air-brake system, the pump lO is dispensed with and the compressed air is let into the pipe 11 by the engineer.

From the foregoing description, taken in connection with the accompanying drawings, the construction, mode of operation, vand advantages of my invention will be readily understood without requiring an extended explanation.

Various changes in the form, proportion, and details of construction may be made within the scope of the invention without depart- IOO ing from the spirit or sacrificing any of the advantages thereof.

Having thus described my invention, what I claim, and desire to secure by LettersPatent, is-

l. In a lubricating device, the combination with an oil-tank having a discharge-orifice and a valve foi` closing said orifice, of a compressed-air pipe communicating with said tank, a valve operated by the admission of air into said tank, and a connection between the last-named valve and the first-named valve, whereby when the last-named valve is opened the rst-named valve will be opened, substantially as set forth.
